The problem it solves
Contractors miss calls. It isn't negligence — you're working with both hands, in noise, often somewhere you can't safely stop. The issue is what happens next: someone who needs a job done now and reached voicemail generally doesn't leave one. They call the next result. You never learn the call happened.
Voicemail doesn't fix this because people don't leave them anymore, and calling back two hours later frequently reaches someone who's already booked with a competitor.
How it works
- 01Someone calls your business number and you don't pick up.
- 02The system detects the missed call, usually within a few seconds.
- 03An automatic SMS goes to that number: an apology, a reason, and a question.
- 04They reply by text — which most people find easier than a voicemail anyway.
- 05You answer when you can safely stop, or someone in the office does.
- 06The conversation stays in one thread, so nothing gets lost between callbacks.
The mechanism is simple. Its value comes from the fact that texting suits both sides of this exchange better than calling does: the customer doesn't have to explain themselves to a machine, and you don't have to stop what you're doing.
What the message should say
Three things: acknowledge the miss, give a human reason, and ask a question that's easy to answer.
- "Sorry we missed your call — we're on a job site. What can we help you with? We'll reply as soon as we're off the roof. — [Company]"
- Always include the company name. An unexpected text from an unknown number gets ignored or reported.
- Ask one specific question. 'What can we help with?' outperforms 'We'll call you back.'
- Keep it under about 160 characters so it lands as a single message.
- Don't sound automated. 'Your call is important to us' reads as a machine and gets no reply.
What it costs
| Option | Typical cost | Notes |
|---|---|---|
| Built into an existing CRM or phone system | Often included | Check what you already pay for before buying anything |
| Standalone missed-call text service | $20 – $50/mo | Simple, quick to configure, does one job well |
| All-in-one contractor CRM | $100 – $400/mo | Includes pipeline, follow-up automation, review requests |
| AI receptionist / answering service | $100 – $500/mo | Handles the conversation, qualifies, and books — the next step up |
Market ranges, not our pricing. Against an average job value in the thousands, the arithmetic is not close — one recovered job typically pays for years of the service.
Rules to follow
Automated business texting is regulated in the US. The essentials for a contractor:
- Register your number for A2P 10DLC through your provider. Unregistered business texts increasingly get filtered before delivery.
- Identify your business in the first message. Anonymous automated texts get reported as spam.
- Honour opt-outs. STOP must work, and your platform should handle it automatically.
- Replying to someone who called you is generally the lowest-risk category of business text — they initiated contact. Marketing blasts are a different matter with stricter rules.
- Keep messages relevant to the call. Don't append promotions to a service reply.
The step beyond it
Missed call text back starts the conversation but still needs you to finish it. If you're missing enough calls that the replies pile up unanswered, the next step is an AI receptionist that answers questions, qualifies the job, captures details, and books the appointment — handing over to you only when there's a real conversation to have.
That's a bigger commitment and worth it at higher call volumes. For most contractors, plain missed-call text-back captures the majority of the available gain for a fraction of the effort. Start there.
Frequently asked questions
- How does missed call text back work?
- Your phone system detects a call you didn't answer and automatically sends an SMS to that number within seconds, usually apologising and asking what they need. The caller replies by text and you continue the conversation when you're able to stop working.
- How much does missed call text back cost?
- Standalone services typically run $20–$50 per month. It's often already included in contractor CRMs and modern business phone systems, so check what you're paying for before adding another subscription.
- Is missed call text back legal?
- In the US, replying by text to someone who just called your business is generally permitted, since they initiated contact. You do need to register your number for A2P 10DLC through your provider, identify your business in the message, and honour STOP requests. Unsolicited marketing texts fall under stricter rules.
- Is it worth it for a small contractor?
- If you miss even a few calls a month and your average job is worth thousands, yes — the maths works after a single recovered job. It's most valuable for solo operators and small crews with nobody in an office to answer the phone.
